White Spots on Fingernails Indicate Calcium deficiency. - Fact or Myth?

Even though the knocking or injury may have happened several weeks ago, the spots show up quite late ; so you may not even realize that this could be the cause.

 Sometimes white fingernail spots could also be a sign of allergic reaction to nail polish or nail hardeners and sometimes a symptom of mild infection. However these white spots on fingernails are temporary and will disappear once your nail grows out but this may take considerable time, even several months.
